摘要: 
Monascus-fermented products have been widely used in Taiwan and other Asian countries as health foods. Unfortunately, many Monascus strains concurrently produce trace amounts of toxic citrinin. This study isolated a strain NPUST-B11 with the ability to degrade citrinin as the only carbon source. The isolated strain NPUST-B11 was characterised and identified as Klebsiella pneumoniae by 16S rRNA gene analysis using UNI-F and UNI-R primers. The isolated strain was then incubated in the mineral broth containing 10 ppm of citrinin, 1.2% of glucose, 0.3% of peptone and 100 ppm of vitamin C under optimal conditions, including pH 7, 200 rpm and 37A degrees C. Citrinin was rapidly degraded with incubation from 97.9% at 1 h to 8.67% at 5 h and completely depleted at 10 h. Overall, this strain could be useful for the degradation of citrinin in food products and other medical applications.
